i need help with my pc cuz i have a tournament coming up
so its an 11hour story from today at 6am till now 5pm i still havent eaten anything anyways i cleaned my pc today morning cuz some ants were going on my desk i deep cleaned everything then my monitor glitched as shown in the first vid then i asked ppl and what i did is i updated my gpu then reseated my gpu and changed the display port for another one then i wanted to determine if it was a monitor issue or pc so using an hdmi cable i hooked up my brothers laptop to my monitor and it worked perfectly so i was confused i used the same hdmi cable to connect the monitor to my pc and it worked but i couldnt use my second monitor as the pc only has 1 spot to plug in an hdmi and my second monitor doesnt support a displayport so i was still trying to fix it and so i tried changing the frame rate to see if maybe the pc isnt refreshing fast enough and i was right anything under 60hz worked but after doing that i plugged in the display port instead of the hdmi and it broke just like in vid 2 so i restarted my pc and pressed f2 which shows the BIOS screen and i reseted everything to default hoping to fix the issue but it became even worse just like in vid 3 i also wanna note that this is a software issue if u see in vid 3 it works perfectly fine(except for the first second in the vid theres a bit of flickering) until i type in my password then it goes into this endless cycle of barely working then burning out and restarting
i dont want this suffering to go on any longer if anyone has any advice please help
sry if my explain is bad if u have any questions feel free to ask (´**༎ຶོρ༎ຶོ`) (i just wanted to use the emoji lwk) ******************************************
also yea i do really have a minecraft tournament in like 2 days
EDIT: my gpu isnt broken (i think) cuz i can run only my second monitor using an hdmi canble perfectly fine
SECOND EDIT IMPORTANT: i commented an image showing how i fucked up if anyone know how to fix that one first i would really apprieciate it
